Abutilon plant named &#39;atn yb5&#39;

ABSTRACT

A new and distinct  Abutilon  plant cultivar is disclosed, characterized by bright yellow flowers, large, glossy leaves, an upright, vigorous growth habit and a tall plant height. The new variety is an  Abutilon , and naturally blooms from April to September.

LATIN NAME OF THE GENUS AND SPECIES

Abutilon vexillarium

VARIETY DENOMINATION

‘ATN YB5’

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The newvariety was discovered as a naturally occurring whole plant mutation. Itwas discovered by Lucilene Anatriello in February 2004 in São José doRio Preto, Brazil.

Asexual reproduction of the new cultivar ‘ATN YB5’ by vegetativecuttings was performed in São José do Rio Preto, Brazil and has shownthat the unique features of this cultivar are stable and reproduced trueto type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ATN YB5’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of‘ATN YB5.’ These characteristics incombination distinguish ‘ATN YB5’ as a new and distinct Abutiloncultivar:

-   1. Tall, vigorous growth habit;-   3. Large green leaves;-   5. Long blooming period; and-   6. Bright yellow petals.

Plants of the new cultivar ‘ATN YB5’ are similar to plants of theparent, ‘Abutilon Yellow’, in most horticultural characteristics,however, plants of the new cultivar ‘ATN YB5’ are taller and morevigorous than the parent. Additionally, the new variety has largerleaves as well as more leaves per lateral branch. The new varietyresists dropping leaves and blooms one month longer than the parentvariety. The new variety ‘ATN YB5’ also has brighter yellow petals.

There is no similar commercial varieties available to compare to ‘ATNYB5’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘ATN YB5’ grown in an outdoor garden with a grouping of15 other plants. The colors are as nearly true as is reasonably possiblein a color representative of this type.
